Doxycycline ‘morning after pill’ cuts STI rates by 80%: largest real-world study
Researcher Dr Michael Traeger (PhD) says he hopes the findings encourage doctors to prescribe doxy-PEP.
Prescribing doxycycline as a morning after pill significantly reduces chlamydia and syphilis incidence following condomless sex between men, according to the largest real-world study so far.
The Australian-led US research looked at 11,500 men who had sex with men (mean age 40) who were already using HIV pre-exposure prophylaxis (PrEP).
It compared syphilis, chlamydia and gonorrhoea incidence two years before the Kaiser Permanente health services in California introduced doxycycline post-exposure prophylaxis (doxy-PEP) and one year after.
Some 2200 patients received doxy-PEP at least once, according to results presented at the International Union Against STIs conference in Sydney last week.
